A new radar imaging system flying over California's complicated network of faults on the belly of a Gulfstream jet is collecting some of the most detailed images yet of the Earth's surface shifting and straining with seismic energy, scientists at NASA's Jet Propulsion Laboratory say. The data from this project could help scientists figure out where the risk of earthquake activity is highest, though the data will never be specific enough to predict a day, location or magnitude of a quake, one geophysicist said.
